The DAT-100 is a simple handheld AES/EBU digital audio generator designed to assist cinema technicians in chasing down digital audio problems.

The DAT-100 has two 25 pin output jacks to drive equipment with the DCI or DMA8 digital audio pinout. Substitution of the AES/EBU source with the DAT-100 allows the technician to determine if a problem is in the source, the destination, or the cable between the two. The DAT-100 can also be used for a quick check of downstream equipment such as crossovers, power amplifiers, speakers, and the speaker wiring. If audio from the DAT-100 is heard in the auditorium, the equipment is working properly. The DAT-100 allows the user to select which of the 16 audio channels is being driven. It may also be used as a quick check to verify that the appropriate speaker is being driven by each audio channel.
